php web indexer?

Hi guys, I'm looking for a PHP/MySQL based http site indexer - I won't want to do filesystem searches, I want to do something like a standard web search engine (like google) performs for my site. I was hoping to make use of an existing search engine (open source) rather than write a custom search module for my site. I was looking at products like: lucene (java I know, and text based indexer) http://jakarta.apache.org/lucene/docs/index.html htdig - looks interesting, but no windows distribution except through cygwin (I think) http://www.htdig.org/ PhpDig - lots of french scattered about, couldn't get it to work properly (suspect doesn't run on php 4.3.x) http://phpdig.toiletoine.net/ At the moment, I'm leaning towards just doing an on-the-fly fulltext search in mysql of my content field in my CMS, but I was keen to see if I could find a generic http indexer for better results more quickly. cheers, neko
